Consider the reaction. 2Pb(s)+O2(g)⟶2PbO(s)

An excess of oxygen reacts with 451.4 g of lead, forming 317.3 g of lead(II) oxide. Calculate the percent yield of the reaction.

percent yield:

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion

All cells are made of four types of acids, lipids, proteins, and carbohydrates.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
